Sex combs reduced (Scr), a Hox gene located in the Antennapedia complex of Drosophila melanogaster, is required for the proper development of the labial and first thoracic segments. The Tribolium castaneum genetically defined locus Cephalothorax (Cx) is a candidate Scr ortholog based on the location of Cx in the beetle Homeotic complex and mutant effects on the labial and first thoracic segment...

BACKGROUND Accurate assessment of renal function is important in the management of patients with kidney disease yet is often difficult to obtain. Formulae, designed for clinical use, have been developed to predict glomerular filtration rate (GFR) utilizing serum creatinine (Scr). Additional parameters are included in these formulae to account for variations in Scr due to differences in total bo...

BACKGROUND Symmetric dimethylarginine (SDMA) is a screening tool for early kidney dysfunction and monitoring treatment in cases of chronic kidney disease (CKD). There are no current studies describing the suitability of this test for use with published population-based reference intervals. HYPOTHESIS/OBJECTIVES To determine the components of biological variability, the index of individuality ...

The roles of three homeotic genes, Ubx+, Scr+, and Antp+, in the Drosophila thorax have been studied by determining the cellular phenotypes of mutations resulting in loss of gene function. The principal results are: (i) The Scr+ and Ubx+ genes are required in the prothorax and metathorax, respectively; in the absence of these genes, both segments develop like the mesothorax. (ii) The Antp+ gene...

Sex Combs Reduced (SCR) activity is proposed to be required cell nonautonomously for determination of tarsus identity, and Extradenticle (EXD) activity is required cell autonomously for determination of arista identity. Using the ability of Proboscipedia to inhibit the SCR activity required for determination of tarsus identity, we found that loss-of-EXD activity is epistatic to loss-of-SCR acti...

Diesel vehicle should be equipped with emission after-treatment devices as NOx reduction catalyst and particulate filters in order to meet more stringer diesel emission standard. Urea-SCR is being developed as the most efficient method of reducing NOx emissions in the after-treatment devices of diesel engines, and recent studies have begun to mount the Urea-SCR device for diesel passenger cars ...

The marginal effects of acute kidney injury on in-hospital mortality, length of stay (LOS), and costs have not been well described. A consecutive sample of 19,982 adults who were admitted to an urban academic medical center, including 9210 who had two or more serum creatinine (SCr) determinations, was evaluated. The presence and degree of acute kidney injury were assessed using absolute and rel...

As part of an improvement project on the linear accelerator at SLAC, it was necessary to replace the original thyratron trigger generator, which consisted of two chassis, two vacuum tubes, and a small thyratron. All solid-state, fast rise, and high voltage thyratron drivers, therefore, have been developed and built for the 244 klystron modulators. The rack mounted, single chassis driver employs...

Background—Acute kidney injury (AKI) is a risk factor for long-term adverse outcomes, including acute myocardial infarction and death. However, the relationship between severity of AKI and in-hospital outcomes in the setting of acute myocardial infarction has not been well documented. Methods and Results—The study population (n 59 970) was drawn from the Acute Coronary Treatment and Interventio...
